Rose plant named &#39;yowipi&#39;

ABSTRACT

A distinctive cultivar of Hybrid Tea Rose plant named ‘Yowipi’, characterized by its dark green leaves; long, thick and dark red stems; large white and pink flowers with ruffled petal margins; and good postproduction longevity.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a new and distinct cultivar ofHybrid Tea Rose plant, botanically known as Rosa hybrida, commerciallyproduced as a cut flower, and hereinafter referred to by the name‘Yowipi’.

[0002] The new cultivar is a product of a planned breeding programconducted by the Inventor in Salinas, Calif. The objective of thebreeding program was to develop new cut Rose cultivars with attractiveflower petal colors, long and strong stems, dark green leaves and goodpostproduction longevity.

[0003] The new cultivar originated from a cross made by the Inventor in1996 of an unnamed proprietary selection, as the female, or seed, parentwith the cultivar Tango, not patented, as the male, or pollen, parent.The cultivar Yowipi was discovered and selected by the Inventor as aflowering plant within the progeny of the stated cross in a controlledenvironment in February, 1999, in Madrid, Cundinamarca, Colombia.

[0004] Since March, 2000, asexual reproduction of the new cultivar bygrafting on Rosa Manetti rootstocks in Madrid, Cundinamarca, Colombia,has shown that the unique features of the new cultivar are stable andreproduced true to type in successive generations of asexualreproduction.

SUMMARY OF THE INVENTION

[0005] The following traits have been repeatedly observed and aredetermined to be the unique characteristics of ‘Yowipi’. Thesecharacteristics in combination distinguish the new Hybrid Tea Rose as anew and distinct cultivar:

[0006] 1. Dark green leaves.

[0007] 2. Long, thick and dark red stems.

[0008] 3. Large white and pink flowers with ruffled petal margins.

[0009] 4. Good postproduction longevity.

[0010] Plants of the Hybrid Tea Rose can be compared to plants of thefemale parent, an unnamed proprietary selection. In side-by-sidecomparisons conducted by the Inventor in Salinas, Calif., plants of thenew cultivar differed from plants of the unnamed proprietary selectionin the following characteristics:

[0011] 1. Flowering stems of the new Hybrid Tea Rose have more thornsthan flowering stems of the unnamed proprietary selection.

[0012] 2. Plants of the new Hybrid Tea Rose have white and pink-coloredflower petals whereas plants of the unnamed proprietary selection havepink bi-colored flower petals.

[0013] Plants of the Hybrid Tea Rose can be compared to plants of thefemale parent, the cultivar Tango. In side-by-side comparisons conductedby the Inventor in Salinas, Calif., plants of the new cultivar differedfrom plants of the cultivar Tango in the following characteristics:

[0014] 1. Plants of the new Hybrid Tea Rose have much longer floweringstems than plants of the cultivar Tango.

[0015] 2. Flowering stems of the new Hybrid Tea Rose have more thornsthan flowering stems of the cultivar Tango

[0016] 3. Plants of the new Hybrid Tea Rose have larger flowers thanplants of the cultivar Tango.

[0017] 4. Plants of the new Hybrid Tea Rose have white and pink-coloredflower petals whereas plants of the cultivar Tango have white andorange-colored flower petals.

[0018] Plants of the new Hybrid Tea Rose have not been observed underall possible environmental conditions. The phenotype may varysignificantly with variations in environment such as temperature, light,water status and/or fertilizer type and rate, without, however, anyvariance in genotype.

BRIEF DESCRIPTION OF PHOTOGRAPH

[0019] The accompanying colored photograph illustrates the new HybridTea Rose plant, showing the colors as true as it is reasonably possibleto obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Hybrid Tea Rose. The photograph comprises a side perspectiveview of a typical flowering stem of the new Hybrid Tea Rose grown inMadrid, Cundinamarca, Colombia.

DETAILED BOTANICAL DESCRIPTION

[0020] The following observations and measurements describe cutflowering stems of plants grown in Madrid, Cundinamarca, Colombia, inpolyethylene-covered greenhouses with day temperatures ranging from 14to 20° C., night temperatures ranging from 4 to 8° C., and light levelsranging from 3,000 to 5,000 foot-candles. Flowering stems used in thephotograph and the description were about 75 days old.
